[Asterisk-Users] Billing (itemized) in the UK

[David J Carter]

Pete,

I am also in the UK and I have added an include in my extensions.conf for
the file listed bellow.

exten => _15X,1,Dial,${TRUNK}/BYEXTENSION
exten => _147X,1,Dial,${TRUNK}/BYEXTENSION
exten => _NXXXXX,1,Dial,${TRUNK}/BYEXTENSION
exten => _01.,1,Dial,${TRUNK}/BYEXTENSION
exten => _07.,1,Dial,${TRUNK}/BYEXTENSION
exten => _08.,1,Dial,${TRUNK}/BYEXTENSION
exten => _09.,1,goto(nogo,1)

You dont need a 9 for a line, you couls also add lines for barred numbers


Regards

Dave

Thank you very much for the answer! I think it is a good path to look at. I
have had a look through
our paperwork for the present pbx, and I found one document that seemed to
indicate we have to dial

1666<extn><dialled_number>

to give the extn info to the telco. The paper is a bit old (1999) and since
then we have changed our
telco, but I guess that this protocol is still valid. This afternoon I will
hook up a recording
device on the line and see which digits are actually dialled when I dial an
outside line. From the
recording I should be able to reconstruct which digits have actually been
dialled by the pbx.

If the protocol is correct, I could construct a dial command such as

exten => _9.,1,Dial(Zap/g1/1666<ID>${EXTEN:1})

or so - I would just need a way to construct <id> - and then any caller from
an inside device would
just prepend a '9' before the real number. I probably would also bar simple
'9' dialling to get an
outside line... lets see.


Keep you posted, and so many thanks for all the help!
